ABSTRACT

Background: The mortality of cutaneous melanoma has not declined over the past 50 years, and the only interventions that can reduce it are primary prevention and early diagnosis; the dermoscopic evaluation is essential to achieve this. Dermoscopy identifies characteristics of melanoma that would go unnoticed to the naked eye. The aim of this paper is to report the most frequent dermoscopic findings in patients diagnosed with melanoma. Material and methods: Contact dermoscopy was performed using dermatoscope LED Dermlite^MR and camera Dermlite^MR; the findings evaluated were asymmetry in two axes, association of colors, lack of pigment, irregular points, atypical network, pseudopods, blue veil, ulceration and perilesional pink ring. Dermoscopic findings were compared with the histological diagnosis. Results: 65 patients with cutaneous melanoma were included; 10 in situ and 55 invasive. The mean Breslow was 3 mm. Most patients (35) had localization in extremities. In all of them the most frequent dermoscopic finding was asymmetry in two axes, followed by association of two or more colors and pseudopods in invasive melanoma. Conclusion: Asymmetry in two axes is the most common dermoscopic finding in melanoma either in situ or invasive; the presence of two or more colors in a pigmented lesion should be suspicious of an invasive melanoma.
